Paving the SeafloorBrick by Brick
Most of Earth’s crust is manufactured at the bottom of the sea. Deep beneath the waves and beyond our view, magma erupts along a 40,000-mile volcanic mountain chain that bisects the ocean floors and encircles the globe. The lava flowing from these mid-ocean ridges solidifies into new ocean crust that spreads out and paves the surface of our planet.

Listening Closely to ‘See’ Into the Earth
Today, excitement and anticipation is growing because of new generations of seismographs designed for use in the oceans. These new instruments will comprise a new national pool of instruments for use by the scientific community.
Shifting Continents and Climates
Sixty-five millions years ago, dinosaurs had just become extinct, and mammals were starting to dominate the planet.
Moving Earth and Heaven
The mountains rise, are lashed by wind and weather, and erode. The rivers carry mud and debris from the mountains into the ocean, where they settle onto the relatively tranquil seafloor and are preserved. The sediments bear evidence about where they came from, what happened to them, and when. By analyzing, measuring, and dating these seafloor sediments, scientists can piece together clues to reconstruct when and how fast their mountain sources rose to great heights millions of years ago, and how the climate and other environmental conditions may have changed in response.
Seeding the Seafloor with Observatories
Scientists extend their reach into the deep with pioneering undersea cable networks
H2O (Hawaii-2 Observatory) – In 1998, scientists used the remotely operated vehicles (ROV) Jason and Medea to create the pioneering long-term seafloor observatory called H2O (Hawaii-2 Observatory). They spliced an abandoned submarine telephone cable into a termination frame. The frame relays power and communications to a junction box, which serves as an electrical outlet for scientific instruments.
The Remarkable Diversity of Seafloor Vents
Since 1982, I had spent most of my waking hours examining pieces of seafloor vent deposits that had been recovered during a routine dredging operation along the Juan de Fuca Ridge off the Pacific Northwest coast.
When Seafloor Meets Ocean, the Chemistry Is Amazing
Scientists are discovering that abundant quantities of methane gas are continually seeping from the seafloor throughout the oceans. This widespread but overlooked natural phenomenon has potentially dramatic implications on world energy supplies, life in the oceans, and Earth’s climate.
Conduits Into Earth’s Inaccessible Interior
Jules Verne wrote about a way to journey to the center of the earth, but unfortunately, we haven’t found it yet. So we really don’t know what happens deep inside our planet.
The Engine that Drives Earth
Poets and philosophers have celebrated the timelessness of the land around us for eons, but the solid Earth is actually a very dynamic body. Great tectonic plates are in constant motion at Earth’s surface.
